Pretty long story, apologies for that in advance, but I'm currently seeing this happen to my wife's extended family. Pretty much her whole family lives in NJ except her dad's youngest brother who lived in Florida with his partner, and her dad's oldest brother who moved down to Florida a few years ago. So dad's little bro got diagnosed with pancreatic cancer almost two years ago, and died this past fall. Big brother didn't think very highly of little bro's lifestyle and partnership with another man throughout the years, so they never got along well. Even after older bro moved to Florida, they rarely saw one another for the first year or so until the diagnosis.
So fast forward to last summer when things were taking a turn for the worse for little bro. We knew there wasn't much time left. All of a sudden, big bro is letting him stay at their house, taking him to and from the doctor's office, giving the family daily updates on his condition, etc. Most of the family saw this as a good thing because even though it was at the end of little bro's life, it looked like big bro was trying to make amends for the way he had treated little bro in the past. Spoiler alert - that wasn't his motive.
Little bro died in November. Family assumes the will and insurance money is going to his partner, who he's been with for a decade or so. Through conversations with the partner, it gets revealed that the decision was made to split the insurance money between partner and the four living siblings. Well at some point last summer, the will was changed. I don't know if my math is 100% correct but from what I'm told, three of the siblings received about $5,000 each, partner received around $40k, and big bro got a little over $100,000!
The biggest concern was why the partner was given such a small share, and they apparently looked into whether the deceased uncle was in the right frame of mind when these changes were made. It's such a shame, because it's always been a tight-knit family. Christmas Eve, all this stuff came to the forefront and was a huge blow-up. First, big bro and his wife denied that they received that much money. They argued that they "only" got $40k. Big bro stormed out of the house and his wife yells from the car back to everyone and said, "If you wanted the money, then you should have been down in Florida taking care of him all this time like we were!"
I mean it was beyond awful.
The cruelest part of that is that Christmas Eve is when deceased uncle used to make his annual trip up to NJ with his partner to see the family. Heartbreaking to see that the first Christmas Eve without him, the family was basically fractured. So yeah...bad times.
